On my 03, there is a lite epoxy and holding clips. The holding clips I've only seen along the doors, but not the hatch doors. To remove it is easy, to replace it takes time and do-overs to get them on just right. (And of course, the Armorall)
Al, do you mean the rubber surrounding strip on the body that the door(s) meet? Not much- you may have to remove or loosen a couple of clips (like the upper innier door trim by the headliner) to give it room, but they just pull off. The doors, both hatch pieces (window and hatch) and the hood are all held on my friction and a lite epoxy, but not "glued" down by any stretch. The bottoms of the doors have some small ones held in my little mini-christmas tree pins
Have you actually removed and replaced the weatherstripping?
Only removed it to run cables through the seat belt pillar. Then popped it right back on. No need for epoxy unless it's new weatherstripping. (I was shown by the shop how to do this)
I have bought new door jamb weather strips for a few of my doors. It shrinks with age, and they aren't too expensive. I think they were under $50 each. The plastic trim should be removed to easily get them off. There is a steel inner core which has a spring tension which holds them on.
Don't bother trying to transplant used stuff, it will be shorter than new, and leave a gap or not fit the corners.
When installing them start where you want the seam at the bottom. Give plenty of material to each corner, don't try to stretch it through the corners. If it is installed naturally(no stretching or crushing - length), there should be a hair of extra length at the other end. That is what you want, evenly spread the bottom sections so that they meet and have a little pressure against each end. That way it will not leave a gap for a long long time at the seam. If never removed it doesn't usually show any shrinkage. Regards,
